Freezing Cauliflower (Spring)
General preservation or storage guidance
Cauliflower florets freeze well for cooked dishes when blanched briefly, cooled promptly and packed with room for expansion.
Method
- Choose a fresh, firm spring cauliflower. Remove leaves, rinse the head and divide it into even florets about 2.5–5 cm (1–2 in) across.
- Blanch the florets in boiling water for 3 minutes. Use batches small enough for the water to return to a boil promptly.
- Drain and cool immediately in cold water until thoroughly chilled; drain well again.
- Pack into freezer containers, leaving about 1.3 cm (½ in) headspace. Seal, label and freeze promptly.
- Use from frozen in cooked dishes. Keep continuously frozen and do not refreeze after thawing.
Storage
Freezer at −18°C or colder · Keep continuously frozen; no exact quality period stated

Pickling Cauliflower (Spring)
General preservation or storage guidance
This tested sweet-sour cauliflower pickle uses a measured 5% vinegar mixture, pre-cooks the florets and is processed in a boiling-water canner.
Method
- For about nine half-pint jars, measure 12 cups (about 2.8 L) of 2.5–5 cm (1–2 in) cauliflower florets, 4 cups (950 ml) white vinegar labelled 5% acidity, 2 cups sugar, 2 cups thinly sliced onion, 1 cup diced sweet red pepper, 2 tbsp mustard seed, 1 tbsp celery seed, 1 tsp turmeric and 1 tsp hot red-pepper flakes.
- Wash the cauliflower, remove stems and blemished parts, and separate into even florets. Boil the florets for 3 minutes in water containing 4 teaspoons canning salt per US gallon (3.8 L); drain and cool.
- In a large pan combine the measured vinegar, sugar, onion, red pepper and spices. Bring to a boil and simmer for 5 minutes.
- Distribute onion and pepper among prepared jars. Fill with florets and hot pickling liquid, leaving 1.3 cm (½ in) headspace; remove air bubbles, wipe rims and fit lids.
- Process hot half-pints or pints in a boiling-water canner for 10 minutes up to 305 m (1,000 ft), 15 minutes from 306–1,829 m (1,001–6,000 ft), or 20 minutes above 1,829 m (6,000 ft). Follow the NCHFP process and altitude table exactly.
- Cool jars undisturbed, check seals and refrigerate any unsealed jar. Store properly processed sealed jars cool and dark; refrigerate after opening.
Storage
Cool, dark storage for properly processed sealed jars; refrigerate after opening or if unsealed · Follow the tested NCHFP recipe; no additional shelf life is claimed
